Move docker systemd unit creation to docker role Creating the unit using default settings early on and then changing it during network_plugin section leads to too many docker restarts and duplicated code. Reversed Wants= dependence on docker.service so it does not restart docker when reloading systemd Consolidated all docker restart handlers. 2016-08-02 10:42:27 +00:00			`TasksMax=infinity`
Configurable docker yum repos, systemd fix * Make yum repos used for installing docker rpms configurable * TasksMax is only supported in systemd version >= 226 * Change to systemd file should restart docker 2017-08-09 22:49:53 +00:00			`{% endif %}`
